Phys.org / Handheld scanner delivers lab-quality chemical composition maps using infrared light
Researchers have developed a compact, handheld mid-infrared imaging spectrometer that can produce high-resolution chemical maps of a sample without using stains or labels. With further development, the handheld device might ...
Phys.org / Tyrannosaurus rex teeth reveal a body temperature close to the human average
When picturing a scaled, toothy Tyrannosaurus rex stomping across North America, building nests and eating other dinosaurs, it's easy to forget that scientists have gleaned everything we know about T. rex from clues left ...
Phys.org / Earth's atmosphere is getting less dusty: That could be adding to global warming
Atmospheric desert dust has long swirled around the globe, but a new UCLA study presents the strongest evidence yet that global dust is mysteriously decreasing. Because atmospheric dust has a slight overall cooling effect ...
Medical Xpress / The body's warmth sensor is secretly a pain switch—blocking it may ease arthritis
Chronic pain, including arthritis pain, affects more than one-third of U.K. adults. Current painkillers such as methotrexate and nonsteroidal anti-inflammatory drugs (NSAIDs) work by damping down the immune system, which ...
Tech Xplore / Harvesting hot electrons could break solar panel barrier
Physics predicts that no more than 33% of the solar energy that falls on a solar panel can be converted into electricity. However, experiments and simulations by scientists at the University of Groningen in the Netherlands ...
Medical Xpress / Stable frontal signals, flexible hippocampal ones: How the brain preserves context as goals change
While humans are completing a task, they can temporarily store information in their minds while also manipulating and adapting it based on changing circumstances. To support this capability, known as working memory, the brain ...
Phys.org / Beaver reintroduction improves peatland water storage and drought resilience
A study led by a doctoral researcher at the University of Liverpool has found that beavers may help restore degraded peatlands by keeping landscapes wetter and making them more resilient to drought.
Phys.org / Sixteen new fungus species found hiding in Thailand's flowers
Researchers have discovered 16 new species of fungus living unnoticed inside garden flowers and wildflowers across northern Thailand, more than quintupling the number of such fungi known to occur in the country. The findings ...
Phys.org / Tendon cells can rebound from stiffness when returned to softer tissue-like surroundings
Researchers at Queen Mary University of London are closer to understanding tendinopathy, a common condition that can cause persistent pain and impaired movement in people and many animals.
Tech Xplore / A robot that shifts its own weight to cross land, steps, and water
A robot meant to inspect a coastline, a flooded street or a wetland can't count on one kind of ground. It might need to crawl over a hard surface, climb a bank, scale a curb or a step, then slide into open water, often within ...
Phys.org / Robotic lab sets up and runs optics experiments on demand
Every new generation of phone display, television screen and solar panel is the result of precision optics experiments, which use lasers and other light sources to measure the optical properties of candidate materials. These ...
Medical Xpress / AI tool nears psychiatrist-level accuracy
UTHealth Houston researchers have developed an artificial intelligence system that can perform a mental health evaluation at nearly the same level of accuracy as a team of psychiatrists. The results of their work, done in ...
